Privacy Policy

Last updated: October 3, 2026

This Privacy Policy explains what information EngKor ("we", "us") collects, how we use it, and your choices. It applies to engkorkorean.com and the EngKor Service.

1. What We Collect

Account information: name and email address.

Profile information: your time zone, your role (member or leader), and your challenge cohort.

Submissions: the writing screenshots and speaking audio recordings you upload as part of the daily challenge, and the leader feedback written about them.

Payment information: we do not collect or store your card or PayPal account details. Payments are handled entirely by PayPal; we only receive confirmation that a payment succeeded and basic billing status.

Technical and usage information: standard information your browser sends automatically (such as general device/browser type) as part of normal web hosting on Cloudflare Pages, plus the analytics described below.

1-1. Cookies and Similar Technologies

We use cookies and similar technologies for two purposes:

• Google Analytics (GA4): collects anonymized usage statistics (pages visited, general device/browser type, approximate location) so we can understand how people use the Service.
• Microsoft Clarity: records how you interact with the page (clicks, scrolling, and session playback) so we can spot confusing or broken parts of the Service. Clarity is configured to mask sensitive input fields where applicable.

Neither tool is used for advertising, and we do not use third-party advertising trackers. You can opt out by: (1) using your browser's cookie/site-data settings to block cookies from this site, (2) installing the Google Analytics Opt-out Browser Add-on, or (3) using a browser tracking-protection or ad-blocking extension that blocks Clarity/Analytics scripts. Blocking these does not affect your ability to use the Service.

2. How We Use Your Information

• To create and manage your account and route you to the correct dashboard (member or leader).
• To let your assigned leader review your writing and speaking submissions and give you weekly feedback.
• To calculate and display your streak, completion rate, and the community leaderboard.
• To process your monthly payment and manage billing (via PayPal).
• To communicate with you about your account or the Service (e.g., confirming signup, billing notices).

We do not sell your personal information to anyone.

3. Who Can See Your Submissions

• You can always see your own Submissions and feedback.
• Your assigned challenge leader can see your Submissions to provide correction and feedback.
• Other members cannot see your Submissions. The community leaderboard only shows names and a completion percentage, never the underlying content.

4. Processing Entrusted to Third Parties / Where Your Data Is Stored (처리위탁 및 국외이전)

We entrust the processing of your personal data to the following third parties to operate EngKor. Several of these process data outside Korea, which is necessary to provide the Service; by using the Service, you consent to this transfer.

• Supabase (United States / AWS infrastructure): authentication and database hosting; stores your account info and Submissions.
• PayPal (United States): payment processing and billing; receives your name and the amount charged.
• Google LLC (United States): Google Analytics (usage statistics) and, if applicable, email delivery via Google Workspace/Gmail.
• Resend (United States): transactional email delivery (e.g., feedback notifications).
• Microsoft Corporation (United States): Microsoft Clarity, for on-page behavior analytics and session recording.
• Cloudflare, Inc. (United States): website hosting and content delivery (Cloudflare Pages).

Each of these providers processes only the data necessary for its function and is contractually or by policy restricted from using your data for its own purposes.

5. Data Retention and Destruction (보유기간 및 파기절차)

We keep your account and Submissions for as long as your account is active. If you delete your account or ask us to, we will destroy your personal data and Submissions within a reasonable time, by irreversibly deleting electronic files (not merely hiding them from the application) from our database and storage.

Exception: payment-related records (e.g., transaction amount, date, and payment confirmation) are retained for 5 years as required under Korean e-commerce consumer protection law, even after account deletion, after which they are destroyed in the same manner.

6. Your Rights

You can:

• Request a copy of the personal data we hold about you.
• Ask us to correct inaccurate information.
• Ask us to delete your account and associated data.
• Stop applying for future months at any time (there is no subscription to cancel; see our Terms).

To exercise any of these, contact us at engkorproject@gmail.com.

7. Children's Privacy

EngKor is not directed at children under 14. We do not knowingly collect information from children under 14.

8. Privacy Officer (개인정보 보호책임자)

EngKor's privacy officer is Jisoo Lee, reachable at engkorproject@gmail.com, for any questions, concerns, or complaints about how your personal data is handled.

9. Changes to This Policy

We may update this Privacy Policy as the Service evolves. We will post the updated version here with a new "Last updated" date, and notify active members of material changes.
